BALING-PRES'S.

Specification of Letters Patent.

Patented Oct. 15, 1907.

Applioatin filed April 25, 1907. Serial No. 370,233.

To all whom it "may concern: Be it known that I, JOHN J. STOPPLE, a citizen of the United States, residing at Dallas, in the county of Dallas and State of Texas, have invented certain new and useful Improvements in Baling-Presses, of which the following is a specification, reference being had therein to the accompanying drawing.

This invention relates to improvements in baling presses, and particularly to a manually operated baling press.

The object of the invention is the provision ofmcans for facilitating the compression of material into bales.

Another object of the invention is the improvement of the construction of the baling press disclosed in my Letters Patent No. 785,642, dated March 21, 1905.

With these and other objects in view, the invention consists of certain novel constructions, combinations, and arrangements of parts. as will be hereinafter fully described and claimed.

In the drawings: Figure 1 is a perspective view of a baling press constructed in accordance with the pres cnt invention. Fig.2 is a longitudinal, vertical, sectional view of the baling press depicted in Fig. 1. Fig. 3 is a horizontal, sectional view of the structure depicted in Figs. 1 and 2. Fig. 4 is a view in elevation of the rear end of my baling press. Fig. 5 is a transverse, sectional view taken on line 5, 5, Fig. 2, and looking in the direction of the arrow. Fig. 6 is a plan view of the fulcrum-member. Fig. 7 is a rear view of the division block. Fig. 8 is a perspective front view of the division block. Fig. 9 is a fragmentary, perspective view of my improved baling press, showing one of the bearings for the lower end of the lever. Fig. 10 is a fragmentary view of a portion of my baling press, showing particularly the spring-attaching hook. Fig. 11 is a perspective view of one of the sleeve-bearings for the lower end of the fulcrum-member.

Referring to the drawings, 1 designates the runners supporting the frame of the baling press. The frame comprises transverse supporting beams 2, upon which is secured the floor 3. The rear end of said floor terminates at 4, Fig. 2, providing an open space 5. Sidepieces 6 extend rearwardly from'the sides 7 of the compression chamber, and longitudinally-extending cleats 8 are secured between the sidepieces 6. Hopper 9 is supported upon the frame, constituting the compression chamber. Ohannel-irons'or guides 10, substantially "(I-shaped in cross-section, are positioned upon the longitudinally-extending cleats or boards 8 and against the inner faces of the sidepieees 6, constituting a guide-structure upon each side of the compression chamber of my baling press.

The inner ends 10 of the channel-irons or guides 10 project into the compression or baling chamber, and their rear ends are positioned preferably in the same transverse plane with the rear ends of the side-pieces 6. The ends of the channelirons or horizontal guides are open, for the purpose hereinafter specified. The plunger-head comprises, preferably, a pair of vertical uprights 11, secured to horizontal pieces 12, and a facepiece 13 is secured to said vertical uprights 11 and said horizontal pieces 12' Suitable braces 14 are secured to the uprights 11 and the horizontal pieces 12 for strengthening the whole plunger head. The facepiece 13 of the plunger head is provided with horizontal grooves 15 and with notches 16 and 16. Secured to the top of face-piece 13 is, preferably, a metallic reinforcing strip 17. Secured to the bottom of said facepiece 13 is, preferably, a metallic reinforcing strip 18, the ends 18 of which constitute spurs extending into the channel-irons or horizontal guides 10, see Figs. 2, 4, and 5. The face-piece 13 of the plunger-head is notched or cut-away, as at 19, Fig. 5, so as to permit the ends 18 of the guide strip 18 to work freely in said channel-irons or guides 10, see Figs. 2 and 5. The guide-strip 18 is, preferably, of greater width than the face-piece 13, see Fig. 2, so as to give greater rigidity to the plunger-head as it compresses a charge of mate'- rial in the compression or baling chamber. By reason of the peculiar structure of the guides 10, plunger head and the guide-strip 18, I form the sides of the compression chamber solid. The strength of the press is materially increased by forming the sides thereof solid, because the sides of the compression chamber will not warp or shrink, or otherwise alter its shape.

Secured near-the lower end of each of the uprights 1.1 are vertical bearings 20. In these bearings 20 is journaled a shaft 21, and a lever 22 is mounted upon shaft 21, preferably, near its upper edge 23, see Fig. 2. The extreme lower end of lever 22 works between the uprights 11, see Fig. 4. Upon opposite sides of the lower end of the lever 22 there are secured reinforcing plates 24.' A vertical reinforcing bolt 25 eX- tends through the lower end of the lever, thereby strengthening the same contiguous to the aperture within which shaft 21 is positioned. By reason of the reinforcing bolt or member 25 and the plates 24, the strength of the bearing end of the lever is greatly increased. Positioned contiguous to the outer face of each bearing 20 is a horizontal pin 20, see Fig. 9, which braces and strengthens the structure, and said pins resist lateral strain upon the bearings 20 and the lower end of the lever.

An auxiliary bearing block .27 is countersunk in the lever, near its lower end, which bearing block 27 is secured in position by means of a primary bearing block 28. The primary bearing block 28 is provided with diametrically opposite extensions 29, which extensions 29 are secured to the lower edge of the lever by any suitable fastening means, as for instance, bolts 30, which bolts are provided with ordinary nuts upon one end. The lever 22 is pivotally mounted upon a fulcrum-member 31. The fulcrum-member 31 is, preferably, substantially V-shaped, and is provided with an upper end 32 and legs or sides 33. Each leg terminates at its lower end in a laterally-extending horizontal short or stub shaft 34. The upper end of the substantially V-shaped fulcrum-member is rounded, at 35. The rounded or cylindrical portion 35 of the fulcrum member 31 is positioned between the bearing blocks or members 27 and 28, and the stub shafts 34' are journaled in the bearing-sleeves 36, which sleeves are secured to the side-pieces 6. Each sleeve is provided with a tubular body portion 37 and with a disk-like end 38. The disk-like ends 38 of sleeves 36 are preferably positioned against the inner face of the side-pieces.

Between the lower end of the lever and the bearing blocks 27 and 28, is secured an eye-bolt 40, which extends, preferably, from the lower face of said lever 22. A substantially U-shaped spring-attaching hook 41, provided with hooked ends 42, is detachably secured to a horizontal transverse, reinforcing rod 43. This reinforcing rod 43 strengthens the side of the frame of my baling press, and, owing to the fact that it is contiguous to the channel-irons or guides 10 and in the path of movement of the horizontal pieces 12,

' it also serves as a stop for limiting rearward movement of the plunger-head, as the ends of horizontal pieces 12 will engage the reinforcing rod 43, as shown in Fig. 2. A coiled spring 44 is attached, at one end, to eye-bolt 40, and at'its opposite end, to the springattached hook 41. When the outer end of the lever 22 is swung downward, causing the same to pivot upon its fulcrum-member 31, the strain upon the spring will be such as to return the lever to its substantially vertical position as soon as the operator releases the same, because the plunger head slides freely in the compression chamber. Secured transversely of and contiguous to the outer ends of the horizontal pieces 12, is an auxiliary guide strip 18 the ends of which are positioned in the channel-irons or guides 10, the same as the ends of the guide-strip 18. It will be obvious that there are two guide-strips working in the channelirons or guides 10, thereby preventing the plungerhead from sagging or working loose. Furthermore, by reason of the open-ended structure of the channelirons or guides 10, no foreign substance can interfere with the free working of the plunger-head, as the guide-strips 18 and 18 will force any material collecting in said channel-irons or guides out at the ends thereof, thereby automatically cleaning the grooved structure of the compression or baling chamber, constituted by said channel-irons or guides 10.

In addition to thereinforcing, horizontal rod 43, I also provide primary angle bracing brackets 45 and auxiliary bracing brackets 46, which brackets 45 and 46 are secured to the frame outside of the compression or baling chamber.

A stop 47 is secured to the bottom 3 of the compression chamber near the front end thereof. The stop 47 comprises a roller 48 journaled upon a shaft 49, which shaft 49 is bent, at 50, and provided with outwardlyextending portions 5]., which portions 51 are, preferably, countersunk or embedded into the floor 3. The roller 48 is positioned in an aperture 52 of the floor and extends, preferably, two-thirds of its diameter above the upper face of the floor and in the path of movement of the division-block 53. The division-block 53 is provided at its upper and lower ends with pairs of lugs or extensions 54, producing central notches 55. The roller 48 is adapted to be positioned within the lower notch of the division-block 53, see Fig. 2. the inner face of the division-block, and near its upper and lower ends, are, preferably, horizontal, metallic plates 56, which plates connect the lugs or extensions 54, thereby preventing outward movement of the division block 53, after the roller 48 and roller 57 engage said plates 56.

The roller 57 is journaled in a bifurcated depending portion 58 of the latch 59, which latch 59 is pivotally mounted, at 60, in the batten or horizontal, longitudi nally-extending strip 61, of the frame. The latch 59 is provided with a forwardly extending handle 62, which normally rests upon the transverse beam 63. A locking-member 64 is pivotally mounted, as at 65, upon beam 63, and said member 64 is bent, at 66, and provided with a handle 67, see Fig. 1, extending above the handle 62 of latch 59, so that when said handle 52 is in its normal position and the locking-member 64 is parallel with the beams 63, swinging movement of the latch upon its pivot 60 will be prevented, thereby holding the roller 57 in the path of movement of the divisionblock 53. Upon swinging the handle 67 of the locking member 64 outward upon its pivot 65 and swinging the latch 59 upwardly upon its pivot 60, the division-block can be removed, and, subsequently, a bale may be easily passed over the lower roller-stop with comparatively a small amount of friction, which is not true with a fixed or immovable stop.

Pivotally mounted in elongated slots 66 formed in the sides of the frame, are dogs 67, which dogs 67 are provided with noses 68, extending into the compression or baling chamber. The nose of each dog is adapted to work within a notch 16 of the face-plate 13 of the plunger-head. Each dog 67 is provided with an outwardlyextending ear 69, which car extends beyond the vertical plane in which the outer side of the frame of the compression chamber is formed. A vertical pin 70 is positioned in the car 69, near its outer end, and the extended portions of pin 70, projecting beyond the upper and lower faces of the ear and normally pressed against the outside of the frame, for limiting inward pivotal movement of the dog. Each dog is also provided with an auxiliary ear or lug 69, preferably near its inner end, see Fig. 3. A short spring 71 bears, near its outer, free end 72, upon the outer end of the auxiliary ear or lug 69, and said spring is fixedly secured near its opposite end, by any suitable fastening means, as screws 73, to the outside of the frame. It will be obvious that a charge in the baling or compression-chamber may swing the dogs outward upon their pivots when passing the same, but said dogs will not permit the charge to expand rearward after the noses 68 have been Secured to positioned behind the charge, by reason of the charge being moved beyond the dogs.

Owing to the peculiar structure of my improved press, the plunger-head can be operated with comparative ease, and by reason of the peculiar structure of the division-block and the roller-stops therel'or, the division-block and a bale can be freely removed from the baling chamber.
